The United States Air Force does not have a First Sergeant rank. It is instead a duty denoted by a diamond within the upper field. They usually act in the capacity of a Senior Enlisted Advisor to a Squadron Commander.

Only one individual was awarded the rank of General of the Air Force, semi-retroactively. General of the Army "Hap" Arnold was awarded the rank in 1949, two years after the establishment of the United States Air Force as a separate body from the United States Army. General Arnold was considered inactive at this time [although not retired, as five-star generals do not officially retire from service], so this rank has never been awarded to an officer of the modern USAF while on active duty.
